SAME PLACE.

COIN-OPERATED INDUCTION=COIL.

$PECIFICATION forming part of Letters Patent No. 393.624. dated November 27. 1888.

Application filed May 11, l8F8. Serial No. 273,642.

.To all whom it may concern:

Be it known that I, GHARLEs DURIEUX, a

citizen of Belgium, residing at New Orleans, in v the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Coin-Operated Induction Coils; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in an automatic electric shocking-machiue,in which a coin is made to operate in conjunction with a lever, rods, battery, and spur-wheels; and the objects of my improvements are to provide a device whereby an electric shock may be rece ved by simply depositing a nickel or other com in payment for such service. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a front view; Fig. 2, a side sectional view.

Similar letters refer to similar parts through out the several views.

The mechanism is contained within a suit able case, A, on the front of which is an indicator with hand 0, the arbor of which extends to the interior of the case, and there carries a pulley, Q, hereinafter referred to. The front is also provided with a slot, D, for the reception of a coin of proper denomination,and with handles (electrodes) A and B, the handle A extending into the interior of the case and being movable longitudinally. Within the case a spring, P, is secured to the handle A,and maintained normally in a retracted position. From the inner end of the handle A to a pulley, T, extends a cord, 1), so that when the handle is moved outward the pulley T will be revolved. On the same shaft with the pulley Tis alarger pulley, S, to which a cord, 5, is secured, and extends under a pulley, R, around the pulley Q, to a spring, 0, which maintains the said cord constantly taut." In thelower part of the case is a coinreceptacle, V, and extending from the slot D to a point above the said receptacle is a coin guide, L. Under the lower end of the guide L is one end of a lever, E, which is pivoted at G and there carries a double pawl, G. A spring, U, keeps the lever E nor- (No molel.)

mally in ahorizontal position. One end of the pawl G engages a rack-bar, F, arranged to move vertically, and the other end of the pawl engages a ratchet wheel, 6, which in turn meshes with gear teeth of a spring-drum, 7. The arbor of the drum 7 carries a gearwheel, 8, which meshes with a gear, 9, carrying an arm, 12, and which gear in turn actuates a governor-fan, 10.

The rack F has its lower tooth, F, deeper than the other teeth, for a purpose which will presently appear. Moving with the rack is an arm, H, arranged to make contact with the terminals K when the rack is lowered. One of the said terminals K is connected with one pole of a battery, M, by the wire 2, and the other terminal is connected to the primary circuit of an induction-coil by the wire 4, the coil being in circuit with the battery. The coil being of the wellknown form used in medical batteries, no description is here given.

The secondary circuit passes to the handle B through wire 1, and also to a leg-electrode, X, and to the handle A through the wire 3. The movable core-sheath N of the inductioncoil is connected with the cord 5.

When a coin is dropped into the slot D, it passes through the guide into the lever E, and, depressing the same, falls into the receptacle V. The downward movement of the lever disengages the pawl G from the rack and from the ratchet-wheel 6. The rack then falls and the arm H contacting with the terminals K the primary circuit is established from the battery to the primary circuit of the induction-coil, to wire 4, to one terminal K, to arm H, to the other terminal K, to wire 2, to battery. If the handles be now grasped, the induced current will pass from the secondary circuit of the coil to wire 1, to electrode B, (or X,) to the user, to electrode A, to wire 3, to coil. By pulling the handle A outward the pulley Sis revolved to wind thereon the cord 5, which in turn draws the coresheath from the coil and increases the induced current. At the same time the cord 5 causes the needle C to move and indicate such increase. When the geartrain is released from the pawl G, the several wheels slowly revolve under the action of the spring within the drum 7, and the arm 12 is broughtinto engagement with the teeth of the rack F and is raised the distance of one tooth to each revolution of the wheel 9. The pawl G falls into the teeth as the rack is raised and holds it in the elevated position. hen the rack has been elevated untilthe pawl falls into the deep tooth F and the arm H is raised from the terminal, thus breaking the circuit, the additional travel of the said pawl is sufficient to bring it into engagement with the ratchetwheel 6, and therebystop the revolution ofthe gear-train. When the handle A is released, the springs P and O carry all the parts to normal position, and they cannot be again operated until a coin is deposited.

The spring that drives the gear-train may be wound up from time to time.

Havingdescribedtheinvention,whatIclaim 13- 1. The combination, with a battery and induetioncoil, of a circuit-closer consisting of the rack F, arm H, spring-actuated gear-train 6, 7, 8, and 9, the arm 12 on the wheel 9, and the lever E, with the double pawl G, and a coin-guide, L, with its lower end over one end. of the said lever E, substantially as specified.

2. The combination, with the battery and induction-coil, of the coin-guide, the lever E, double pawl G, the rack F, with the deep tooth F, the arm H, carried by the rack and arranged to close the primary circuit of the battery and coil, as described, the motor-gear 7 8, the ratchet-wheel 6, driven by the gear 7 and engaged by the pawl, and the wheel 9, carrying the arm 12', substantially as specified.

3. The combination, with the battery and induction-coil, of the coin-guide L, the movable handle A, the cord 5, connected thereto and to the movable core-sheath of the coil, an indicator'needle also connected to the cord, and a circuit-closer consisting of the lever E, the double pawl G, carried thereby, the racl; F, engaged by said pawl, the arm H, carried by said rack, the motor-gear 7 8, the ratchetwheel 6, driven by said gear and arranged to be engaged-by said pawl, and the wheel 9, with the arm 12, also driven by said motor-gear, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
